我正在嘗試向我的模型添加唯一驗(yàn)證，但當(dāng)我嘗試更新數(shù)據(jù)時出現(xiàn)錯誤。桌子：acq_m_budgets==================================budget_id serial NOT NULL,budget_code character varying(15) NOT NULL,budget_name character varying(100) NOT NULL,ma_code character varying(10),start_period timestamp without time zone NOT NULL,end_period timestamp without time zone NOT NULL,budget numeric(16) DEFAULT 0,credit numeric(16) DEFAULT 0,debet numeric(16) DEFAULT 0,balance numeric(16) DEFAULT 0,reserve numeric(16) DEFAULT 0,created_by character varying(100) NOT NULL,created_on timestamp without time zone DEFAULT now(),updated_by character varying(100) NOT NULL,updated_on timestamp without time zone DEFAULT now(),CONSTRAINT PK_AcqMBudgets PRIMARY KEY (budget_id),CONSTRAINT UN_AcqMBudgets UNIQUE (budget_code)我的模型：AcqMBudgets.phpclass AcqMBudgets extends Model{    public $timestamps = false;    protected $primaryKey = 'budget_id';    public $sortable = ['budget_code', 'budget_name', 'ma_code', 'balance', 'updated_on'];    protected $fillable = ['budget_code', 'budget_name', 'ma_code', 'start_period', 'end_period', 'budget', 'credit', 'debet', 'balance', 'reserve', 'created_by', 'created_on', 'updated_by', 'updated_on'];        protected $attributes = [        'budget' => 0,        'credit' => 0,        'debet' => 0,        'balance' => 0,        'reserve' => 0,    ];    在模型上，我已經(jīng)將創(chuàng)建和更新方法的規(guī)則分開了。不同之處在于 updateRules() 中，規(guī)則數(shù)組中需要一個主鍵參數(shù)。在控制器的update功能上，出現(xiàn)錯誤，指出：SQLSTATE[42703]: Undefined column: 7 ERROR: column "id" does not exist LINE 1: ...from "acq_m_budgets" where "budget_code" = $1 and "id" <> $2 ^ (SQL: select count(*) as aggregate from "acq_m_budgets" where "budget_code" = N01 and "id" <> )。我使用的主鍵是整數(shù)和增量，但由于某些情況，主鍵的名稱不能只是id，所以我將其更改為budget_id并已在模型開頭聲明它。根據(jù)錯誤消息，Laravel 似乎一直在嘗試與該id字段而不是我聲明的字段進(jìn)行比較。需要做什么來解決這個問題？
